TRENDS IN SIERRA NEVADA TREE MORTALITY
On March 14, 2019 a workshop on tree mortality was held at the U.S. Forest Service Wildfire Training Center, McClellan, CA. The workshop was organized and hosted by the University of California. At that meeting, data gathered by various researchers was shared with attendees, most of whom were representatives of state and federal agencies. Information on live and dead trees, bark beetle attacks, regeneration and forest fuels was presented in a series of short talks and roundtable discussions. Some of the highlights of the meeting were:
• Brittany Dyer of American Forests and co-chair of the State’s Tree Mortality working group presented an excellent historical overview on how the Sierra counties affected by tree mortality responded and urged the governor to declare the tree mortality disaster.
• Latest data indicate that there are 149 million dead trees in California, up from 129 million last year.
• In the Sierra Nevada, the amount of new tree mortality increased in a north to south direction based on sampling conducted in 2017. In 2018, sampling indicated that new mortality has increased in the northern Sierra and decreased somewhat in the central and southern Sierra. The biggest decrease is in the central Sierra.
• Mortality due to bark beetles has declined substantially over the past year.
• Falling dead trees were studied with the highest rates of fall in white fir, followed by incense cedar and sugar pine. Ponderosa pine fall rates are lowest (one percent/year). Overall, 62 percent of dead trees fall in whole or part within three years.
• There is evidence that wildfire severity increases if there is a combination of standing dead trees and dense forest stands.
All the presentations from the workshop are now posted on the project web page: http://ucanr.edu/treemortalitynetwork .

RIGHT OF ENTRY (ROE) FORMS
There are many properties with dead trees potentially affecting County roads where owners have not returned Right of Entry forms to allow the assessment of dead trees and their removal. Dead trees along County roads on private property not only represent a threat to the roads but they are a liability to the property owner. If trees fall and damage roads or cause damage or injuries to travelers, the private property owner may be responsible for compensation. In some cases, trees that threaten County roads also threaten houses and other assets. If you receive a Right of Entry form you are urged to return it as soon as possible. The benefits of the County program include removal of the trees at no cost to the property owner and alleviation of
the hazards posed by the trees. If you have received a Right of Entry form in the mail you are urged to return it. Please note that only property owners who receive these forms are qualified to participate in the program. If you think you may have trees qualified for removal by the County contact Dr. Richard Harris, Amador County Tree Mortality Coordinator at (707) 685-5508 or rrharrisconsulting@gmail.com.
